Eruhantalë was a Númenórean rite, the last of the Three Prayers to Eru said each year by the King of Númenor.
The Eruhantalë signified thanksgiving to Eru, held at the end of each autumn. The King would ascend the "Pillar of Heaven", the mountain of the Meneltarma, accompanied by a silent, white-clad crowd of his people. He would offer the prayer on the mountain's summit, while three Great Eagles, the Witnesses of Manwë, hovered above.
